Lithium Battery for Electric Bike - Battery Life Expectations

By Addmotor | 25 November 2022 | 0 Comments
The human body is designed for cycling. Considering how much energy is consumed to move a person over a certain distance, cycling is the most efficient form of personal transportation. Think about what would happen if cycling was made even more efficient.  

The answer lies in e-bikes. There are many benefits to riding an electric bike, including being healthy and having fun. When you are riding a motorcycle, you can feel the wind and sun on your face, watch the scenery go by, and enjoy your ride like a kid.

The battery on electric bikes is one of the most important and expensive components. The battery powers the electrical components of your fat wheel electric bike. So, the battery will decide how long you can ride the bike without recharging it, how long it will work, how much it weighs, etc. Therefore, it is imperative that when you choose an electric bike, you should pay most attention to its battery.

Like the battery in your car, an electric bike’s battery has a useful lifespan that only lasts so long before its performance begins to deteriorate. The batteries of an electric bike aren't cheap. They are usually 1/3rd of the price of your long distance electric bike. So, you must know what you're selecting and how long it will last. In this blog, we will discuss the battery life expectations of your electric bike.

Battery capacity

The capacity of a battery is the amount of energy that can be stored in the battery on one charge. It is one of the main and most important specifications to consider for any battery as it will determine how much energy you can store. The unit used to measure this capacity is ampere-hour. Depending on the brand and type of battery, the capacity can vary from the one given in the battery description.  

The capacity of any battery does have an influence on the total life expectancy of the battery. There is a certain number of charge cycles that batteries can withstand before their capacity declines proportionally. The battery is considered to have been discharged two cycles if they had discharged it 20% and then recharged it.

Depending on the operating conditions of the battery, the battery life is determined by the number of cycles. The longer we discharge the battery, we can expect fewer possible cycles from it.

The UL-certified 48V*20Ah battery pack used in most of the electric bikes from Addmotor features Samsung's latest high-capacity 21700 battery cell combination, which provides larger cell capacity as compared to other brand batteries.

Charge cycles

Cycle life will profoundly affect battery performance. During their lifespan, batteries are measured in cycles, and their performance can decline as they approach the end. Those batteries that are nearing the end of their useful life will not hold the charge as long or last as long as new ones. Cycle refers to the act of charging and discharging a battery once. There can be a variation in the number of cycles available based on the quality of the cells in the battery.

 The UL-certified 48V*20Ah lithium-ion batteries on Addmotor's long range electric bike are rated as 1000-1500 charge cycles per battery. However, to get the most out of your battery, you should know how to take care of your battery.

Life expectations

The lifetime of a lithium-ion battery can be expected to range between 3 and 5 years. After that, the battery will still work, but not for long. The holding energy capacity will decrease, and your battery will discharge quickly and not provide you with enough range as it used to provide. However, this expected life also depends on a few factors which include the added weight, usage of your e-bike, the condition you ride in, the capacity of your battery, and maintenance of your battery.

In terms of weight, the more weight there's on your bike, the harder the motor will have to push, which will derive more power from the battery, draining it quickly. The usage of your e-bike is also important as if you take your bike to hilly areas or uneven roads, battery drainage will be fast. The weather and how you maintain your battery will also have a direct effect on your battery's lifespan.

The electric bike with longest battery life range uses the new UL-certified battery packs in Addmotor's collection and can provide up to 125+ miles on a single charge.

Final words

The life expectancy of any battery depends on various factors, including battery type, storage capacity, charge cycles, and how you take care of your battery. After taking care of a few factors, you can keep them working for longer. Batteries aren't cheap either, so spending some extra on getting UL-certified batteries makes a lot more sense in the longer run.
